Growth and survival of post-settlement sea urchins

摘要: This chapter discusses the growth and survival of sea urchins. Growth in echinoids means change mass, diameter and, shape test, which requires expansion, calcification, production soft tissues. Skeletal is based on cellular processes that result both changes during rates change. Echinoid skeletons consist ossicles include spines, elements Aristotle's lantern, plates test are attached to each other by small projections collagen threads. The skeletal attributes provide information for interpreting overall body as well measures environmental conditions. also focuses following cohorts field, does not appear have been done with urchins, or can be combining transitions size–frequency data these methods applied
